FAQ
What information do you need to fix the bug?
A description of the issue, steps to reproduce it, and access to the code (GitHub/GitLab). Screenshots or a screen recording help me start faster.
Can you fix bugs in an app someone else built?
Yes, that's most of my orders. I work with existing React, Next.js, Node.js, and MERN codebases daily, regardless of who wrote them.
What if the bug is more complex than expected?
I'll tell you before doing extra work — never a surprise charge. We'll agree on a custom offer if the scope genuinely changes.
What if you can't find or fix the bug?
If I genuinely can't fix your issue, I'll tell you honestly and we'll cancel — you don't pay for no result. This hasn't happened yet.
Will your fix break something else?
No. I find the root cause instead of patching symptoms, and I test around the change before delivery.
Do you provide code optimization and refactoring?
Yes, as part of the Premium package or as a gig extra — performance tuning, query optimization, and cleanup.
Can you also add new features?
Yes, small features are available as a gig extra. For a full application build, check my full stack development gig.
Is my code confidential?
Completely. I never share, reuse, or publish client code, and I'm happy to work under an NDA.
